Hey can you guys recommend me an amp that will do well with ~250-300ohm cans? My current amp can get them loud, sure, and I'm not sure if it's just the nature of dynamic speakers or they're not being given enough current, but on faster/busier passages there's like.. bits of pause between sound where it seems like it can't keep up. Like ~microstuttering~ due to clipping.

on that note I'm considering orthos in my future so this amp would have to power those, too. What will work here and not be :homebrew: ?

e: Schitt Lyr or Valhalla maybe?

Here's an interesting comparison of hi-res audio to CD and MP3:

https://www2.ia-engineers.org/iciae/index.php/icisip/icisip2013/paper/viewFile/160/146

In the comparison between hi-res and 128kbps MP3 (newest LAME version), 55.6% preferred hi-res over MP3. That's not exactly a resounding win for hi-res audio.

Read through the paper and see how many questions you have for their testing methods and procedures, because holy hell there are a lot of iffy parts to it. Like for instance, why are they using CBR instead of VBR for MP3? Does anyone actually use CBR anymore except maybe 320kbps (and they really should be using -V0 or lossless instead)?

Isn't it obvious that CBR 128 kilobit is used because it's about the minimum quality most people will accept out of MP3s intended for full range music (as opposed to something all acapella or an audiobook)?

Like yeah, if they tested it with V0 MP3 even fewer people would prefer hi-res to that mp3, probably, but that's not as damning as "we used the worst common MP3 bitrate and still 45% of people were ok with it".

Pretty much, and 128kbps used to be the standard bitrate for MP3s back in the bad old days of Napster, Xing Audio Catalyst and Audiograbber. Which is the whole reason why MP3 still has a bad rap these days, because crap 128kbps was claimed to be "CD quality", when it so obviously wasn't anywhere near that.

128kbps with a modern version of LAME is much better, and VBR is a complete game changer. Transparency for most people on most music happens around -V5, which is around 130kbps average, but allows for higher bitrate when needed. So 128kbps is kinda OK I guess, and they did include the highest possible quality MP3 (320kbps) as well, for comparison.

I just find it very odd that comparatively fewer people were able to distinguish hi-res audio from low-bitrate MP3, than were able to distinguish high-bitrate MP3 from low-bitrate MP3.

And since they repeatedly mention the (controversial) work on the so-called "hypersonic effect" by Oohashi et al., even going so far as to use the exact same Pioneer super-tweeter, it seems pretty obvious that the paper was meant to champion hi-res audio as something beneficial. And not, you know, completely pointless and a waste of space.

Every major breakthrough in audio technology (78s to microgroove LPs, LPs to CDs, cassette tape to literally everything else) has been completely obvious to anyone who has listened to both formats, but it just ain't happening with hi-res audio. We've had SACD since 1999 and DVD-audio since 2000, but both were miserable failures, and while hi-res audio downloads exist (HDTracks, Pono etc.), I think it's fair to call them a statistical anomaly at best.

And yet the audiophile press keeps harping on about how much of a giant leap in sound quality hi-res audio supposedly is, when the supposed benefits just aren't there at all. It's an amazing example of a shared delusion.

Phrasing it like this is almost misleading, in a sense. It's more likely that, say, 80%+ of them didn't actually hear a difference at all, of which roughly half guessed "right" and the other half guessed "wrong" about what the higher quality source was. Much more than 45% of them would be "ok with it" if such a thing was really the case.

The other thing with SACD and DVD-Audio is that they're really hard for the average joe to get a player that plays them in full quality. Yeah some SACDs also have a side encoded in regular CD format, and many DVD-Audio discs have a fallback encode in regular DVD audio format so you can play them in anything, but their benefits absolutely don't exist in those lower encodings. So if you want to actually listen to anything done new, you still gotta spend a lot of money. And you can't, say, play back SACD on a computer (because they were worried about piracy) and it's really annoying to get a setup that will handle DVD-Audio on a PC.

Even if they were amazing, the price and hassle is prohibitive for people. It'd be like if CD players stayed as expensive as at launch until like, 1998.

Plus DVD-Audio's whole "story" isn't helped by the fact that a regular DVD with audio stored normally is already at supremely high quality - the standard DVD player specifications since like 1999 allow for up to 7.1 channels at really high bitrate and 7.1 surround with 48k sampling rate, or up to 5.1 with 96k sampling rate in a different codec. You're basically completely set with standard DVD player quality audio even if high sampling rates and higher sampling depths (24 bit per sample is supported) are "neccesary" to you.

I just remembered that I got a measurement mic along with my dbx Driverack PX DSP box-o'-magic, so I've just ordered a USB mic preamp and a stand+cable, so I can try out REW and get some measurements.

It'll be fun to see how my EQ that I've dialed in by ear actually measures up.

I'm about to get some VERY modest ~@!~audiophile~!@~ gear. Reading reviews online has been helpful, but it's like listening to a bunch of cranky old wine tasters. One guy says headphone amp A is bright. Another says it's neutral. Another says it's musical. So...which is it?!?!!?! Yeah, yeah, I gotta go listen to this stuff myself. Luckily I live in a city with several high end dealers. And don't get me started with cable talk. And no, Mr. Reviewer, I'm not going to spend $9,000 for a Bricasti M1 DAC, are you crazy?!?

That's pretty much how I see it going down. The gear that makes me smile (within my budget) is what I go home with. And for once, instead of going in like a know-it-all, I'm gonna let the salesperson do some recommending. It'll be a nice change, and I can always guide them if I feel they're going astray with my wants and needs.

I do a lot of fiddling, building my own tube headphone amplifier and so forth, and I'm always planning on what sort of ridiculous thing I'll buy once I have more money and a proper room to put it in and so forth. But the article linked a few pages back from the founder of Stereophile made me reflect a bit about actually reproducing what sounds real and I realized I've only ever experienced it in two distinct cases, with totally different systems.

One is with fully horn loaded systems, like the vintage Klipsch stuff, and at the ridiculous top end, the Edgarhorn Titans. Especially for rock and roll, they sound incredible just because they sound like Pro/PA speakers to a large degree and have effortless midbass power (but not necessarily super bass extension).

The other was a fullrange single driver horn loaded speaker (A fostex Sigma 208 in a double back horn), in this case the Cain & Cain BEN.

I remember one of the grumpy old guys on the audioasylum forums talking about how you can always tell when you walk past a bar if there's a real band inside or just a stereo, and obviously it's not the 'soundstage' or frequency response or anything. But those two setups have it for me, regardless of the reason.

I don't even remember the electronics hooked up to them, and I can't imagine it matters.

Due to psychoacoustic and also partly how many years we've grown up with certain inaccuracies/harmonics etc it's often the case that what sounds most 'real' is acutely far from a perfect representation of the original material. See tape saturation in mastering, even order harmonics particularly in bass enclosures, etc.

A huge part of HiFi marketing and tuning is really about their selection of compromises and such rather than really pursuing accuracy, and I think this is why so many of them are against quantifiable testing. That and making fat stacks of cash off gullible idiots and kit addicts, of course.

As someone who used to be a B&O tech, you must've come across this;





...rather than an actual 9000 as those things are loving quality bits of kit, acres of CNC machined aluminium, a large chunk of glass and a mechanism that's super smooth. Also it has a digital out so y'know, it's as audiophile as you could want. It's a sculpture that also plays music.

Not a defender as such, even though I used to work there.

Rattly and chintzy are certainly not words I would put to any B&O product*. Overpriced and sometimes with very divisive designs, yes. But certainly not chintzy. For all of their faults, they know very well that if something looks like metal, it had better be metal, or you're just setting your customers up for disappointment when they actually use the product. And if you use plastic, make sure that it's thick and well-supported, rattles and squeaks are big no-nos.

I don't know which B&O products (or maybe knockoffs) you've used, but they're certainly not the same products that I worked on and was surrounded by while I worked there.

And you gotta respect a remote control that can be thrown hard enough to kill a man, and yet still work perfectly afterwards.

* Although they have made a couple of stinkers over the years. Their MP3 players and their mobile phone were crap, but the materials used were still gorgeous and high quality.

B&O polarizes people like no other audio brand.

I've been around B&O gear since the 70s. Every decade they have one --maybe two-- standout pieces. In the 80s, the Beogram 1800 turntable was very much worth its price, as were the mid-range MMCx phono cartridges that went with it. The current H6 headphones, to me, are a fair deal at $399. It's a crowded market in that price range, lots of good cans with different sound signatures. I happen to like the B&O house sound, and for what I mostly listen to, the H6 delivers.

So overall I'm a fan of the brand, realizing that in many cases one is paying for name recognition and industrial design, not so much for sound, but that also in a few shining instances, the sound matches the price.
